AC Maintenance Checklist: What Homeowners Can Do and What a Tune Up Includes

Your air conditioner works hard through long Oklahoma summers. Like a vehicle, it needs regular care to run well and last. A little maintenance goes a long way toward lower bills, fewer breakdowns, and a longer system life.

What homeowners can do

Monthly

• Check the air filter and replace it when dirty

• Make sure vents and return grilles are open and not blocked by furniture

Every few months during cooling season

• Flush the condensate drain line with about a quarter cup of white vinegar

• Check that water is draining outside where the line ends

Seasonally

• Clear leaves, grass clippings, and debris from around the outdoor unit

• Keep shrubs trimmed back at least two feet from the condenser

• Gently rinse the outdoor coil with a garden hose (power off first, no pressure washers)

• Test your system in early spring before the first hot day

• Replace thermostat batteries

• Test carbon monoxide and smoke detectors

What a professional tune up includes

A Red Rock Mechanical tune up is a thorough inspection and cleaning that typically includes:

• Checking refrigerant pressures and temperatures

• Testing capacitors, contactors, and electrical connections

• Measuring motor amp draw

• Inspecting and cleaning the outdoor coil

• Inspecting the indoor coil and blower

• Clearing and testing the condensate drain and safety switch

• Checking thermostat operation and calibration

• Checking airflow and the temperature difference across the coil

• Lubricating moving parts where needed

• Inspecting ductwork connections we can access

• A written report of anything we find

How often should I get my AC serviced?

We recommend having your cooling system serviced once a year, ideally in the spring before the heat arrives. If you have a heat pump or a gas furnace, a second visit in the fall for heating is a good idea. Heat pumps run in both seasons and benefit from twice yearly service.

Why it is worth it

Regular maintenance can help catch small issues like a weak capacitor before they leave you without cooling on a 100 degree weekend. Many equipment manufacturers also expect regular maintenance to keep warranties in good standing.
